Pasternack has announced a portfolio of high performance zero biased waveguide detectors that exhibit optimum performance in Ka, Q, U, V, E and W frequency bands. According to the company, the waveguide detectors are widely deployed in various aerospace, defence and commercial wireless applications used in instrumentation, power detection, power monitoring, direct detection receivers, high frequency communications, radar, SATCOM, point-to-point radio, telecom, data links and R&D.

Waveguide detectors

The range consists of six unique models covering a broad frequency range of 26.5GHz to 110GHz. The input ports use popular waveguide sizes ranging from WR-28 to WR-10, while the video output ports use SMA female connectors. The detector circuits use high performance GaAs Schottky Barrier Beam lead diodes with extremely low junction capacitance. These designs perform with minimal sensitivity variation resulting in a flat frequency response across the entire waveguide band.

All the devices are zero biased, so no external DC bias or mechanical tuning is required. The package designs use rugged steel construction and are thermally stable. Integrated waveguide connectors make the outline extremely compact. Performance is guaranteed over 0°C to 50°C. These detectors offer negative output voltage polarity for a variety of applications. Typical voltage sensitivity levels range from -600mV/mW to -3000 mV/mW.
